WebJun 2, 2016 · One allpass filter that might be acceptable (if the sinusoid frequency is relatively slow) and would certainly be simpler would be a variable delay. If you needed a phase shift at a finer granularity than a single sample, then you could achieve this through a fractional interpolation filter. For example, look at the Farrow Structure. jci ns8000 manual
